SPECIFICATION forming part of Letters Patent No. 775,942, dated November29, 1904.

Application iiled December 8, 1903. Serial No` 184,311. (No model.) l

Be it known that LJnnrERsoN SITTER, a citizen of the United States,residing at Western Saratoga, in the county of Union and State ofIllinois, have invented certain new and useful improvements in Pea orBean Threshers, of which the following is a specification.

This invention relates to the type of agricultural machinery forliberating peas, beans, and the like from their hulls or pods, itsspecial purpose being to facilitate the work and to minimize the lossfrom crushing or marring the berries commonly experienced in machinesfor this work as heretofore generally constructed.

rlhe invention deals most especially with the threshing mechanism andthe means for feeding the vines thereto, all as will appear more fullyhereinafter and illustrated in the drawings hereto attached, in which-Figure l is an elevation of a thresher and separator embodying theinvention, the threshing and feeding mechanisms being in section. Fig. 2is a top plan View of the threshing-cylinder and rotary beater. Fig. 3is a front view of the retarder located at the juncture of the chute andconcave and cooperating with the threshing mechanism androtary beater.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The threshing mechanism illustrated is of the undershot type andcomprises the concave l and tlneshing-cylinder 2, each being providedwith cooperating teeth arranged in parallel rows and having the teeth ofone row staggered with reference to the teeth of the adjacent rows. Theteeth are of similar construction and are comparatively thin and wideand are arranged with the width iu line with the direction of travel ofthe material through the machine, so as to withstand the strain.

',lhe vines or material to be threshed is fed to the machine along thechute 5, which is in clined toward its delivery end to facilitate thefeeding operation. A retarder is located at the delivery end of thechute and at the entrance to the threshing mechanism and com* prises thetransverse bar (i, teeth 7, and spurs or saw-teeth 8 along' the Lipperedge of a plate 9, attached to the bar 6. The teeth 7 are iet into thebar 6 and are slightly inclined at their upper ends toward thethreshing-cylinder and are spaced apart a distance to admit of thepassage therebetween of the teeth 10 of the rotary beater l1. lhe upperrear corners of the teeth 7 are beveled, which in connection with theinclination of the teeth, permit the vines to ride thereover in theoperation of the machine, so as to ohviate choking. rlhe plate 9 havingthe saw-teeth 8 along its upper edge is provided as an economical mannerof supplying the saw-teeth 8, which engage with the vines and inconjunction with the teeth 7 hold the same while the teeth 4i of thethreshing-eylinder tear through the hulls and liberate the peas, beans,or the like.

The rotary beater is located above the retarder and at the delivery endof the chute 5 and comprises a cylinder ll and teeth l0, the latterbeing arranged in parallel rows around the cylinder and tapered towardtheir outer ends. The teeth l0 operate between the teeth Y and the teethelf and carry the vines forward against the action of the teeth 4i,which engage therewith and move the vines over the concave l and intothe separator.

The material to be threshed, as vines bearing peas, beans, or the like,is supplied to the chute 5 and moved forward to the inner end, when itis taken up by the teeth of the rotary beater and carried forward intothe threshing mechanism, the retarder preventa ing the too rapid feedand holding the vines while the pods or hulls are broken by the teeth 3and a, so as to liberate the berries. The broken pods, the vines, andthe peas are delivered from the threshing mechanism into the separator12, which may 'lie of any construction to effect separation of thematter in the well-known manner.

Having thus described the invention, what is claimed as new is lneombinatioinaJ threshing mechanism coinprising a toothed concave and atoothed cylinder, a chute arranged in a higher plane than the concaveand connected therewith, a toothed the two sets of teeth at the inner ordelivery end of the chute, substantially as set forth.
